Well, an error occured when MOL was reading from the block device.
At the moment, there is no error recovery so the request will
never complete (and OS X will happily wait forever upon the
completion). 

Error recovery should not really be necessary since no errors
should occur in the first place. Actually, I'm aware of a situation
when this error could occur without there beeing an actual error, 
namely if there is a short read (read(fd,buf,size) != size).
Fixing this has been on my to-fix list for some time now... 

Linux devices do not normally return short reads though (unless
there is a signal delivery). It would be helpful if you could add
a few printm statements to src/drivers/disk/ablk.c in order to 
determine if this is indeed a short read, a signal delivery or a real
error (e.g. a read past end of the device).
